Solution 4: 
When the input signal is in positive half diode with 8 V battery will operate: 
Hence equation will be:
Vin8  Vout= Vin-8 
Hence maximum Vout=20-8=12V 
When the input signal is in negative half diode with 10 V battery will operate: 
Hence equation will be:
Vin-10  Vout= 0 
Hence minimum Vout=-20+10=-10V 
Hence option 4 figure d 
Solution 5: 
When there is a drop of 0.8 then 
For positive: 
Hence equation will be:
Vin8.8  Vout= Vin-8.8 
Hence maximum Vout=20-8.8=11.2V 
For negative half:
Vin-10 .8 Vout= 0 
Hence minimum Vout=-20+10.8=-9.2V 
Hence option 4: +11.2 and -9.2 
Solution 6: 
When a battery is applied with saw tooth wave form then the saw wave will shift by 20 volt:
